In the episode Sound EffeXXX, the guys pose as aspiring & fledgling inventors, showing their inventions to a focus group. Joe's first invention was a pair of flip-flops with bricks attached on the bottom. Joe claimed that he invented them to make the Achilles' tendon on the foot stronger, but doomed his chances at winning by saying that he only worked on them for 20 minutes. Despite not getting a vote for the brick flops, he nonetheless secured a win by getting a vote for a similar invention, Rear-View Glasses.
